About one month ago we shared our download numbers and we announced the majority of the lightning users are on Thunderbird 3.x. The numbers showed that roughly 75% of our users now used a Thunderbird 3.x. During the last month some things have changed: Even more users have downloaded lightning for Thunderbird and the number of users who use Thunderbird 3.1 has grown.
In this chart you can see that most users are still using Thunderbird 3.0, but the number of users who use Thunderbird 3.1 is steadily growing and it will lead very soon. The number of Lightning users on Thunderbird 3.1 has been growing very fast in the last two months, which shows that Lightning is a great add-on and people just love it as much as we do.
While the number of Thunderbird 3.1 users is growing, the number of Thunderbird 3.0 users has literally collapsed, although the number of Thunderbird 2.0 users is going down very slowly.
That’s all about Lightning – let us move on to Sunbird!
In this chart you can see the active daily Sunbird users. The average is still moving up, but earlier last month the number was moving down for some weeks. This chart explains itself pretty well, so let us move on again…
Sometimes people are still using an outdated version of Sunbird. Although the development of Sunbird has stopped, you are still able to update Sunbird. Now, you may ask how much the daily growth of updates is. In this chart you can clearly see that the numbers are really random…
So, let us finally compare the download growth of Lightning and Sunbird.
You can clearly see that we got more Lightning users on Thunderbird than Sunbird users. While the number of Lightning users is still growing, Sunbird is almost dying. In the 35-day moving average you can see that the download number was rising for a short while, but suddently just dropped again.
Now, what do these numbers mean for us, the calendar software and its future?
To find this out, you need to have some different angles of view on the download numbers: The future of Lightning seems really good so far, while the future of Sunbird looks very dark. But what have we learned from this? Well, we learned lots of things, for example that some users don’t want to use an application for mail and for calendar – they don’t want to use more than one program, they want to use an add-on that brings the calendar-function to Thunderbird, an awesome mail client, while some users prefer using multiple applications.
We also learned that people really like to have the latest version of software installed, although some people just want to stay on the old versions.
The future of our calendar software seems obvious, but even if you take a closer look at it you can’t really predict what the numbers will look like…
